Determine if a value is in a array

README.md

This is a fork of a function by MathRobin. It's a bit longer, but it's made to work in older browsers that don't support indexOf.

Raw
index.js
function(a,b,c,d){for(c in b)d|=b[c]===a;return!!d}
Raw
test.js
var inArray = function(a,b,c,d){for(c in b)d|=b[c]===a;return!!d}
document.write(inArray("foo",["foo","bar","lorem","ipsum"]))​​​​​
//will write true on the page
